AMD SMI Go interface overview#
The AMD SMI Go interface provides a convenient way to interact with AMD hardware through a simple and accessible API. The API is compatible with Go 1.20 and higher and requires the AMD driver to be loaded for initialization. Review the prerequisites.

Refer to the Go library API reference.
Prerequisites#
Before get started, make sure your environment satisfies the following prerequisites. See the requirements section for more information.
Ensure
amdgpu
drivers are installed properly for initialization.Export
LD_LIBRARY_PATH
to theamdsmi
installation directory.export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/rocm/lib:/opt/rocm/lib64:
Install Go 1.20+.
For example, to install from https://golang.org/dl/go1.20.12.linux-amd64.tar.gz:
git clone https://github.com/udhos/update-golang cd update-golang sudo ./update-golang.sh source /etc/profile.d/golang_path.sh go version
Get started#
Note
hipcc
and other compilers will not automatically link in the libamd_smi
dynamic library. To compile code that uses the AMD SMI library API, ensure the
libamd_smi.so
can be located by setting the LD_LIBRARY_PATH
environment
variable to the directory containing librocm_smi64.so
(usually
/opt/rocm/lib
) or by passing the -lamd_smi
flag to the compiler.
A Go application using AMD SMI must call goamdsmi.GO_gpu_init()
to initialize
the AMI SMI library before all other calls. This call initializes the internal
data structures required for subsequent AMD SMI operations.
goamdsmi.GO_gpu_shutdown()
must be the last call to properly close connection to
driver and make sure that any resources held by AMD SMI are released.
Usage#
For an example on using the AMD SMI Go API, refer to this implementation amd/amd_smi_exporter.

Add AMD SMI library to your project#
To include the AMD SMI Go API in your project, update your Makefile or Go module configuration to fetch the appropriate version of the AMD SMI library.
go get github.com/ROCm/amdsmi@amd-staging
When using a Makefile, ensure you’re fetching the latest AMD SMI repository with Go API support. See amd/amd_smi_exporter for an example implementation.
